There’s jubilation in Tennessee, the final battleground for women who’ve been seeking the vote.

After Congress passed the 19th Amendment, the states still had to approve it. This summer, all eyes turned to Tennessee. Crowds jammed the Legislature: would the amendment make it?

As the “no” votes piled up, supporters watched in despair. Then 24-year-old Harry Burn, the youngest member, abruptly changed his vote to “yes.” The floor erupted in pandemonium as women in the gallery embraced and wept for joy.

Asked why he changed his mind, Harry said his ailing mother sent a letter telling him “to be a good boy” and vote for suffrage.

Leaders like Susan B. Anthony did not live to see this day. But their sisters will vote in November’s election in every state.
